The present application discloses a screen sounding system having a screen, an exciter for driving the screen, and a magnetic element fixedly connected with the screen. The exciter includes a housing with an accommodation space and a magnet arranged in the accommodation space. The housing is fixed on the magnetic element through magnetic attraction force between the magnet and the magnetic element. Compared with the related art, the screen sounding system disclosed by the present application facilitates removal and installation of the exciter. The position of the exciter can be adjusted through slip. Meanwhile, the magnetic element can avoid an influence on the screen caused by a magnetic field of the exciter.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The screen sounding system as described in claim 1, wherein an orthographic projection of the exciter toward the magnetic element completely falls on the magnetic element.
3. The screen sounding system as described in claim 1, wherein the magnetic element is a magnetic-conducting steel sheet.
4. The screen sounding system as described in claim 3, further comprising a middle frame for fixing the screen, wherein the housing comprises a main body part and a connection part extending out along a direction perpendicular to vibration from the main body part; and the connection part is fixedly connected with the middle frame.
5. The screen sounding system as described in claim 4, further comprising a substrate fixed on the screen, wherein the magnetic element is fixed at one side of the substrate far away from the screen.
6. The screen sounding system as described in claim 5, wherein a projection of the main body part along a vibration direction completely overlaps with a projection of the magnetic element along the vibration direction.
7. The screen sounding system as described in claim 6, wherein of the magnetic element is a soft magnet.
8. The screen sounding system as described in claim 6, wherein the magnetic element is glued to the screen.
9. The screen sounding system as described in claim 1, wherein the magnetic element is a permanent magnet.
